Hi everybody!

I am trying to run examples of Lua opcodes. i.e. lua_ikopcall and others.
All of them return 
attempt to call a nil value. 

Any help appreciated.
Thanks!

I just built Csound from Git develop head on Ubuntu 16.04 and the Lua
opcodes work fine.

Things to check:

-- Make sure that you have built and installed LuaJIT 2.0.4.
-- Make sure that your LuaJIT is built for 64 bit CPU architecture
(I'm assuming Csound is) like this:

mkg@Sun-Yukong:~/csound$ file /usr/local/bin/luajit-2.0.4
/usr/local/bin/luajit-2.0.4: ELF 64-bit LSB executable, x86-64,
version 1 (SYSV), dynamically linked, interpreter
/lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.24,
BuildID[sha1]=e07d14d33b446faeacfc4056e10b95f257e2c6fa, stripped

-- Make sure that you see something for LuaJIT when you run ldd on
libLuaCsound.so, like this:

mkg@Sun-Yukong:~/csound$ ldd libLuaCsound.so
linux-vdso.so.1 =>  (0x00007ffd14177000)
libluajit-5.1.so.2 => /usr/local/lib/libluajit-5.1.so.2 (0x00007f9de7443000)
libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f9de7096000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f9de6e7f000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f9de6c62000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f9de6899000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f9de658f000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f9de638b000)
/lib64/ld-linux-x86-64.so.2 (0x00005623a23cb000)

If you don't, make sure that the libluajit-5.1.so.2 is in ldconfig or
in LD_LIBRARY_PATH.

-- You could try setting LUA_PATH and LUA_CPATH environment variables
according to Lua FAQ here: http://www.luafaq.org/.

Send me a csd or Lua file that reproduces your problem and I will try
to debug it.

Best,
Mike

Thank you, Michael! 

The test examples are running OK now. Please check your mailbox.

The attached csd, based on your orc and sco example, works fine. Changes:

-- Fixed typo "csoundLibrary.csoundGetKsmps" to
"csoundApi.csoundGetKsmps." You crashed because csoundLibrary was
undefined.
-- Changed krate kOut and kIn to arate aOut and aIn. You would have
crashed because kOut had one slot but you are indexing ksmps slots.
-- Put in a simple oscillator for aIn to visibly display the inversion
of the signal.

Best,
Mike
